A Comparison of Performance Measures for Online Algorithms

Abstract: Abstract. This paper provides a systematic study of several proposed measures for online algorithms in the context of a specific problem, namely, the two server problem on three colinear points. Even though the problem is simple, it encapsulates a core challenge in online algorithms which is to balance greediness and adaptability. We examine Competitive Analysis, the Max/Max Ratio, the Random Order Ratio, Bijective Analysis and Relative Worst Order Analysis, and determine how these measures compare the Greedy … Show more

“…Not that much is known about the strengths and weaknesses of these alternatives in comparison with each other. In [7], a systematic study of performance measures was initiated by fixing a (simple) online problem and applying a collection of performance measures. Partial conclusions were obtained in demonstrating which measures focus on greediness as an algorithmic quality.…”
